Application filed October 23, 1922. Seria1 Nb.4596,308;

This invention relates to folding machines but is more especiallydesigned with refer ence to machines for folding'a binding .tape aroundthe edge of sheet material.

In the manufacture of shoes, it. has been" customary to provide certainstyles w th what is known as cord bindin Thi s'is accomplishedbystitching'a piece 'oftape or;

suitable fabric to the right sideofthe shoe part or material to be boundat. its edge.

then by turning the binding in a reverse dii'ection over the stitchingand around the edge of the material and by pressing the free ed e of thebindin material downu 2D h V on the reverse side of the shoe partor'otherj material; the engaging surfaces having previously been treatedwith'cement. Since the binding material is turnedin a reverse direction,the stitching is concealed and when the binding is turned tightly andsmoothly around the edge of-th'e material to be bound, a finished andattractive cord edge is presented. that the binding material be turnedtightly andsmoothly about the edge of the/bound material, otherwise thebinding becomes loose and wrinkled when subjectedto wear and destroysthe attractive appearance of the shoes.

The main object of thisinvention isthe provision of a machine adaptedfor this work which contains the minimum number of operatinginstrumentalities, and whichlis of simple construction and operation andyet eflicient.

A further objectis the provision of a gauge so constructed that itguides the ma-' terial through the machine by COHEHC D WIth' the outsidesurface of the upturned bind ing.

Another obyect Other objects of the invention will be. more specificallyset forth and described hereinafter. v

One of the important features ofiny invention resides in the provisionof a gauge substantially perpendicular in its operative portion to thework-support of the machine and extending below it which is adapted toguide the material by engagement with the It is essential in thisworlcof the invention is the provision of a gauge so constructed that it'outside faceofithebinding. In this case the material is heldagainst'the' gaugewith the bindingupturned around its edge and betweenthe" edge of the material'and the; gauge. This permits of theuse of anunyielding gauge which maintains its position and yet does not interfereWith the feeding of the worlr'which is a distinct advantage.

Vvhen work of thischaracter is" guided "by means'of a gauge adapted toengage the edge of the material to be bound above the binding, there atendency for the work to catch onto drag on tlie'end'of the-gaugethereby, causing defective work: By haw ing the binding upturned aroundthe edge of the material when it is held' against the gauge; I amenabled-to set gauge nearer' the turning member or plow" and the bindingis in a" position which facilitates its turning by the -plow without.subjecting its edge to strain.

A'nother'important feature of niy inven tion consists in'coinbiningthegauge with the pressing member and in providing it with serrationsor-teethso that it may be. utilized for wipingthe binding closely upewardly around the edge of thematerial as I it is held against .thegauge. It is very essentialin applying binding'that itbe drawn tightlyaround the edge of the material, otherwise itwillvary in thickness andbecome looseand flabbyin use.

In thedrawin'gsillustrating the preferred einbodiment of'myinvention;Figure 1 is an end elevation ofa portion" of a folding machine having;my invention embodied therein; Fig; 2 is a side elevationof the same asviewed froni'the'operators seat; Fig. 3 is 1 a view in perspective on anenlarged scale 'ofa combined pressing 'member; gauge and I mounted awork-support having a bevi work plate and isprovidedwith a turned- ,endof the lift-shaft 19,.is connected by a link 26 to a stud 27'carried bya split collar 28' secured to the. upper end of the feed-bar 20, and therocking of the'lift-shaft 19 through these hie-ans imparts an up anddown movement to thefeed-bar 20 in the housing 22. The feed'bar isheldin a lowermost positionby a spring 30,- andv the idler roll with whichthe feedfoot co-operates in the feeding movement is loosely mounted upona screw stud 32 set in the end of the lower arm. 2

Through the foregoing, the feed-foot is given a four-motion feed) In itsforward movement (away from the operator) it is in .a lowermostposition, co -operating with the idler roll to feed the material forwardin the machine. At the end of the feeding movement, the rockingv of thelift-shaft 19, through the medium of the arm 25, link 26 and'collar 28,lifts the feed-bar 20 and feedfoot 24: to release the material andholdsthem in a raised position during their movement backward at the end ofwhich they are dropped into initial position. The material is thereforefed in astep-by-step manner. All of the foregoing construction and modeof operation is fully shown and described in said Lautenschlager patentto which reference may behad. p

Upon the end of the lower arm 15is elled edge 51 toward the operatorupon which may be arranged, ifedesired, means for wiping over orstraightening out the binding in a direction away from the material tobe bound as the work is fed through the. machine. The wiper shown isinth'e form of a thin plate 53 having a portion 5 1 bent under thebevelled portion '51 of the up slightly hooked-over thin edge 55, this:edge being oblique to the normal line of feed. As the material is fedthrough the machine, the sharp edge 55engages the bind? ing and sincethat edge runs obliquely from left to right in the direction of thenormal fe-ed,-its effect is to draw the binding away from the materialto which it issecured and thereby straighten it out. i

For turning the binding over and downi "wardly toward the reverses ideof" the material a plow or turner 58 of ordinary. form may hemountedupon the work-support '50.

and independent;

Preferably it is secured to or made integral with a flexible, strip 91,counter-sunk in the work-support 50, and held in adjusted position by ascrew 92. This arrangement permits the plow to yield slightly whenever ashaft 68 mounted in the bearing 7 0 formed on the upper arm 16 and isarranged to oscillate therein. I

Secured in the perpendicular portion of the lever is a threaded screw 72having a check nut 7 3, and provided with a longitudinal hole in its endin which is mounted a spiral spring 7 5. This spring bears against ablock 76, set in an arm 77, fixedly mounted on the end of the lift-shaft19.. Through the medium of these parts, the lever 65 is rocked by theoscillation of the lift-shaft 19 to raise and lower the presser arm andpresser member, and the machine isso timed that the presser member isdown between the feeding movements and elevated during the feedingmovements. To hold the lever 65 in the posit-ion shown in Fig. 1 withthe spring 75 abutting the block 76, a spring set in a hollow screw 81bears against the upper portion of the lever 65. The screw is threadedthrough an arm 83 forming a. part of the upper arm 16 of the machine,and the pressure exerted upon the lever 65 by the spring 80 may. beadjusted by turning the screw one 'way or the other.

The foregoing construction constitutes no part of the present invention.The stationary wiping device and the pressing member are shown anddescribed in an application for Letters Patent filed by me jointly withLorenz Muther in the United States Patent Oflice on July 24;, 1922,Serial No. 576,965,

and the resilient plow or turner is the subject of another applicationto be filed by me.

The novel features of the. present invention reside in the provision ofa new form of gauge and of means for wiping the binding upwardly aroundthe edge of the material. Preferably, in theapplication of my inventionto the folding machine shown, the

gauge and wiper are combined with the pressing member but it is to beunderstood that in the application of my invention to other forms offolding machines, it may be preferable to make said members separate Themachine is then started.

the pressing memberrthe presser-arm'60 may be provided with a.bifurcation 88 which ex tends rearwardly toward the operator and thendownwardly below thelower face of the presser 62through asuitableopening Hl' the'work-plate 50; the bifurcation SS'being so formed thatit is substantially perpendicular to'the work-support at and just abovethe surface thereof, and is sufficiently: long so that it extends belowthe'worz-plate atalltimes. On that portion of the face adapted to en a'ethe work the ause-8811121 be are a t: 9 b o vid'ed'with-serrations orteeth QO (seeFig. 5) so faced as'to' catch thebmdmg on the upwardmovement. only and F to slide over" it on the downward? movement.

The operation of the machine is as follows: The material is presentedtot-he nia between the feed-footand the idler roll, the feed-foot beingin its initial position ready for feeding. In this initial position thework is held: tightly againstthe gauge 88,

the tape at that point being turned upwardly around the edge of thematerial 'tobe bound anduin en moe-m'cnt with the 'auo'e;

7 t: o t: a

mechanism feeds the material one step, the edge ofithe work-slidmgzbythe gauge wlth the binding at that pointinan upright position. Duringthis feeding"movementthe work should be held firmly against the-gaugethe nose of th e plow or turnerytlie binding is turnedi downwardly"toward l the reverse side of the material and at the end of the feedingmovement the pressing member descends and presses the turned-overbinding down upon the cemented reverse side of the material. As thepressing member descends the gauge 88 moves downwardly sliding by thework in engagement therewith. The pressing member remains in pressingposition while the feeding means are returning to initial position andjust before the next feeding movement the presser and gauge are raisedand the teeth 90 on the gauge catch upon the upstanding binding at thatpoint and draw it upwardly tightly around the edge of the material. v

The work is thus fed through the machine in a step-by-step manner, thebinding being wiped upwardly by the upward movement of the gauge while.the work is held stationary by the feed foot. This action takes place asthe presser member is raised from the work just after the feedfo t hascome down upon the work to start the feeding movement. The wiping may befacilitated by holding the work in tight en- The feeding gagement withthe gauge, in which case the binding is drawn tightly around the edge ofthe material.

The advantages of a gauge of the charac ter herein shown and describedare manifold. it does not interfere with the turning of the bindingmaterial tightly around theedge of the material to be bound nor with thenatural curve of the edge of the binding material given by theplowor'turningdevice, since gauge is outside of the binding and g ides thematerial through engagement with the upturned binding.

Since the ploworturning device operates to turn the binding downwardlytoward the reverse side of the material and away from the gaugeyit ispossible to place the gauge in close proximity to the plow andtherebysecure a close grouping of the folding instrumentalities which issoconducii'e to perfectwork.

The use ofagauge having a point adapted for contact with the edge of thematerial above the binding interferes with the turning of the bindingtightly upwardly and around the edge ofthe material at that point andconsequently such a gauge n'mstlbe lo cated a sullicient distance awayfrom the plow or turning device to permitthe tape to turn over naturallywithoutstraining-the edge. This prevents close grouping of the foldinginstrumentalities and the perfect work which is secured by such closegrouping.

In-addition, the close proximity of'my the binding to relaX or withdrawfromthe edge of the" material after it has been wiped upwardly by thegauge and before it is turned downwardly by the plow, in consequence ofwhich a close tight fold is attained.

It is to be understood that my invention is 100 i 7 gauge to the plowgives no opportunity for not to be limited to the exact form or the lexact application herein shown and described. since it may be embodiedin other forms of construction and may be applied to other forms offolding machines all within the purviewof the following claims.
